Question

Factor: 9x²-6x+1

Answer 1

the first term has factors of : 1*9, 3 * 3
the last term has factors of :1*1
( - 1)( - 1) must be the last terms in each (), now try the factors of 9
(3x-1)(3x-1), if you multiply the outside terms you get -3x, if you mulfiply the inside terms you get - 3x, when adds up to -6x

Answer 2

Instead of guess and check, you could use the AC method to get a proper answer.

Answer 3

\[(3x-1)^2\]

Answer 4

(3x - 1)(3x - 1)
3x *3x - 1*3x - 1*3x -1*-1
9x^2 - 6x + 1
